Abstract

The purpose of this study was to evaluate the ionic conductivity as a function of temperature,
range (25 to 75°C) in the imidazolium-based ionic liquids 1-ethyl-3-methylimidazolium chloride
(EmimCl) and 1-butyl-3-methyl imidazolium hexafluorophosphate (BmimPF6) of different
volume percentages under optimal electrolyte combination conditions. The findings revealed that
when 1% EmimCl or 1% BmimPF6 was applied, conductivity decreased significantly in relation to
the Kohlrausch relationship. When 1% EmimCl or 2% BmimPF6 was added, the study showed the
highest coefficient of alpha (α), while beta (β) was the lowest coefficient for temperature. In
conclusion, the influence of the change in volume percentage on the conductivity is weakened by
temperature control.
